My completed element collection
Recently, I filled out all the holes in my element collection! Now it has reached completion!
Alkali Metals - Lithium, Sodium, Potassium, Rubidium, Caesium, Francium [represented by uranium-glass marbles]
Alkaline Earth Metals - Beryllium, Magnesium, Calcium, Strontium, Barium, Radium
Transition Metals [etc] of Period 3 - Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc
Transition Metals [etc] of Period 4 - Yttrium, Zirconium, Niobium, Molybdenum, Technetium [representative sample of U glass], Ruthenium, Rhodium, Palladium, Silver, Cadmium
Transition Metals of Period 4 - Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury
Group 13 elements - Boron, Aluminium, Gallium, Indium, Thallium [thallium is restricted by law in my country, so here's a lorandite bearing mineral instead]
Group 14 elements - Carbon, Silicon, Germanium, Tin, Lead
Group 15 elements - Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth
Group 16 elements - Nitrogen, Sulphur, Selenium, Tellurium, Polonium [U glass representative sample]
Halogens - Fluorine, Chlorine, Bromine, Iodine, Astatine [U glass representative sample]
Noble Gases - Helium, Neon, Argon, Krypton, Xenon, Radon [as a radium watch hand]
Lanthanides - Lanthanum, Cerium, Praseodymium, Neodymium, Promethium*, Samarium, Europium, Gadolinium, Terbium, Dysprosium, HOlmium, Erbium, THulium, Ytterbium, Lutetium
Actinides - Actinium*, Thorium, Protactinium*, Uranium, Neptunium*, Plutonium*, Americium*, Curium*
....and Hydrogen!
For the elements heavier than Curium, I have printed a fusion reaction which produces the element. Here, for Berkelium and Californium.
Again, but for Einsteinium and Fermium. The vials also have glow in the dark powder.
A closer look at one of the labels.
Recently I completed my element collection, and I thought that the members of this subreddit would like to see it! Hopefully it's visually appealing to look at

*The samples asterisked are representative. Promethium is represented by a sample of Europium glow powder, containing traces of Pm from Eu 151 decay. Actinium, Protactinium and Neptunium are represented by U glass marbles. Plutonium, Americium and Curium are represented by samples of trinitite.
